China's bismuth trioxide exports in May rose slightly from April [SMM Data]

According to customs data, China's exports of bismuth trioxide in May 2026 totaled 1,033.611 mt, compared with 898.429 mt in April 2026, representing a slight MoM rebound and a return above the 1,000 mt level. Looking at overall export volume trends, China's bismuth trioxide exports have shown an uptrend almost every month since September 2025, indicating that export enthusiasm among bismuth trioxide enterprises remains solid and demand outside China is also increasing notably. While May exports held above the 1,000 mt level, they still exhibited a continued uptrend. Market participants believe that with Q3 approaching, the market may engage in some advance stockpiling and usher in the summer break; it is highly likely that China's bismuth trioxide exports will continue to increase in June.
